Affected agent applications may launch the newly registered server, expanding their configured tool surface. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.0.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The manifest activates a hook that silently writes agent configuration and registers this package as an enabled MCP server. This is unconsented install-time mutation of an agent control surface, warranting a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-16T21:32:10.814Z - **Finished:** 2026-10-16T21:32:50.664Z - **Download time:** 1023 ms - **Static scan time:** 88 ms - **AI review time:** 38738 ms - **Total time:** 39850 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook silently registers this package as an MCP server in global and project agent configuration files. This creates an agent integration during dependency installation without an affirmative setup step. - **Trigger:** Installing the package runs its postinstall hook. - **Impact:** Affected agent applications may launch the newly registered server, expanding their configured tool surface. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T21:32:50.664Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook writes an enabled hyperglob entry into agent configuration files when one is absent; the entry invokes this package's mcp.js with Node. - **Attack narrative:** During package installation, the postinstall hook adds an enabled MCP server entry to global or project agent settings without requesting consent. That entry launches this package's MCP server, expanding the tools available to configured agents. - **Rationale:** The manifest activates a hook that silently writes agent configuration and registers this package as an enabled MCP server. This is unconsented install-time mutation of an agent control surface, warranting a publish block. - **Files touched:** package.json, scripts/install.js, ~/.claude.json, \/.mcp.json - **Network endpoints:** https://github.com/Nom-nom-hub/hyperglob/releases/latest/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/install.js as a postinstall hook and declares the package as its own dependency., scripts/install.js writes changed configuration files without a consent prompt., The install hook adds an enabled hyperglob MCP server to global and project agent configurations when no entry already exists., The registered command launches this package's mcp.js through Node. - **Evidence against:** The binary download targets the package’s GitHub release path; that endpoint alone does not establish malicious behavior., mcp.js implements file-discovery and import-dependency queries when an agent calls its tools. ## Affected versions and remediation This report applies to @blazeinstall/hyperglob@1.0.4. - Avoid installing @blazeinstall/hyperglob@1.0.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
